Flashing bathroom light - whilst switched off!

Flashing bathroom light - whilst switched off! This is 2 yrs after a complete rebuild. Recently, the bathroom light has started to flash whilst switched off. It flashes very briefly once or twice a second. It's a fluorescent 2D fitting, two wires, no earth. I suspect one of three reasons: a) Problem with the switch that allows a small amount of current through. Seems unlikely. The switch looks fine, and the light switches on and off okay. b) Water ingress into the fitting. But this looks fine. No sign of water damage. And, in any case, it's switched off, so it should have no live feed. (Yes, I know that live and neutral sometimes get muddled up, but even so where's current going to without an earth?) c) Water ingress into the wiring somewhere where I can't see it. This is in a flat, so $deity knows what the person in the flat upstairs lets overflow. Any help would be appreciated.

I have a mint condition one from 2005.

I can confirm that from personal experience, although I don't know what the voltage was. All you had to do was stand under the power lines holding one end of a tube, and it would glow. I let somebody else do it first, before trying it myself!
